Promotion of steel structure residence in need of social power, need more to an executor, developers to bring real benefits, in order to guide them to steel structure residential areas, to achieve industry transformation and upgrading.
Combined with engineering practice, the steel structure of the housing to the developers of the four aspects of the benefits attributed to aspects:
One, the construction speed, save the loan interest and management costs.
Due to the steel components to achieve the production line of continuous process for making, reducing the field workload, also can realize different sub project of the stereo crossover operation, thus the construction period is shortened by about 30%. Construction period shortening on the one hand, accelerate the capital turnover, convenient in advance repaid bank loans, on the other hand also can save a considerable amount of disturbing management fee and project costs such as wages, travel, etc, in the current high interest loans enterprises financial environment, is particularly important.
Two, the main body structure is light weight, reduce the basic cost and seismic cost.
The main structure is different, the basis of the cost is also different. Two systems, the full structure of the high concrete structure. Although the steel tube concrete mixed structure is used in steel, but the amount of concrete is reduced, which makes the structure of the structure significantly reduced, thereby saving the basic cost. Taking Wuhan century home district as an example, if the reinforced concrete structure is used, the vertical load of 1.38t per square meter, the steel structure is only 0.95t. In the southeast coastal area of China, shallow ground bearing capacity is not high, if the multi-layered concrete structure is built, is likely to use pile foundation, but if the use of multi-storey steel structure, for the independent foundation under column provides the conditions. Because the basic form is different, so that the basic cost of the difference between the more.
As the light weight, the structure under the seismic action decreases, also meet the requirements of current national standard premise, the relative can relatively save construction cost more, the more in the area with high seismic intensity is more and more apparent.
Three, high technology content, to become a bright spot in sales.
Steel structure residential high technology, energy saving effect is significant, can create a more safe and comfortable space for residents, as a sales window, can improve the sale rate of real estate.
Beam with a reasonable high frequency welding H steel, can easily meet the 7-9 meter or even greater span. After building structure closely with careful layout of the large column of steel structure residence, not only space transparent flexible, for building flexible layout provides a convenient, also for households according to their own needs for housing reform to create the conditions, which undoubtedly is very popular with the current market welcome.
Four, increase the use of area, both to become a selling point can also bring direct benefit.
Jharkhand CCA board grouting wall thinner ventricular wall only 90mm thick, compared with traditional material wall (150mm to 200mm) range, reduce significantly. Wuhan century residential home, for example, cross-section of frame column only 350mm wall and pillar two and enable the effective use area of the steel structure housing compared with the traditional forms of residential increased 4% - 8%, which actually increases the building use value. At the same time, it also brings a series of benefits:
For garage or shops on the ground floor of the residential, shops and parking spaces area increased, directly increase sales revenue; for commercial housing comprising an area for sale area, for the developers to bring direct economic benefits; for the area of commercial housing sold by the construction area, in the sale of real estate will become the new bright spot to attract consumers. In addition, the basement for the garage of residential or residential buildings with shops, the structure can be easily achieved without the use of expensive conversion measures, without the need to increase the cost of construction.
